▶ [Hotel Industry Application Scenarios]

In the hotel industry, deep groove ball bearings are widely used in high-frequency operating equipment such as luggage carts, linen washing machines, and elevator door operator systems:

• Luggage carts: The low-friction design of single-row bearings reduces cart noise to below 55 decibels (equivalent to normal conversation volume), enhancing guest check-in experience;
• Linen washing machines: High load capacity (dynamic load up to 18.5kN) can meet the continuous washing demand of 200+ sets of hotel linen per day, reducing equipment jamming failures;
• Elevator door operator systems: Combined with sealing structures (such as double-sided rubber seals), it can effectively prevent dust and foreign objects, adapting to dusty environments such as hotel lobbies and guest rooms, and extending the maintenance cycle to more than 12 months.

▶ [Technical Advantages of Single-Row Design]

Single-row deep groove ball bearings achieve dual core values through rolling friction optimization from "point contact to line contact":

1. Dynamic stability: The concentricity error between inner and outer rings is ≤0.01mm, and radial runout is controlled within 0.03mm during high-speed operation, avoiding abnormal noise caused by equipment vibration;
2. Installation flexibility: Supports two installation methods: shaft fixed/housing fixed, which can adapt to the narrow installation space of hotel equipment (minimum installation aperture only requires 31.75mm), reducing construction difficulty.
